Makefile Fixes

Problem Identified

The original makefiles used objects.tmp file-based linking which caused issues on macOS:

GNU Make $(file ...) function unreliable
Temporary file deleted before linking completed
Directory removal race condition

Solution Applied

Changed to direct object file listing in linker command:

# OLD (problematic)
@$(file >$(build_root_path)/objects.tmp) $(foreach F,$(object_files),$(file >>$(build_root_path)/objects.tmp,$F))
@$(linker) ... @$(build_root_path)/objects.tmp ...
@rm -f $(build_root_path)/objects.tmp

# NEW (working)
@$(linker) ... $(object_files) $(object_asm_files) -o $@ ...

Files Modified

gcc/makefile_boot (lines 225-235)
gcc/makefile_appli (lines 420-430)

Flashing

Flash Loader

Location: gcc/MX66UW1G45G_STM32H7S78-DK.stldr
Purpose: Program external flash (0x70000000) for Appli

Flashing Order (CRITICAL)

Boot first (internal flash only)
Appli second (with external FlashLoader)
Reset (press NRST button)

VS Code Tasks

Task	Shortcut	Description
Build Boot	Ctrl+Shift+B	Build only Boot
Build Appli	Ctrl+Shift+B	Build only Appli
Build All	Ctrl+Shift+B	Build both projects
Flash Boot	Ctrl+Shift+B	Flash Boot to internal flash
Flash Appli	Ctrl+Shift+B	Flash Appli with external FlashLoader
Build + Flash Boot	Ctrl+Shift+B	Build & flash Boot
Build + Flash Appli	Ctrl+Shift+B	Build & flash Appli

Verification Commands

# Verify build artifacts exist
ls -lh Boot/TouchGFX/build/bin/*.hex Appli/TouchGFX/build/bin/*.hex

# Verify HEX format (should show ASCII text)
file Boot/TouchGFX/build/bin/target.hex
file Appli/TouchGFX/build/bin/target.hex

# Test STM32CubeProgrammer
